embassy building is really just down the block from where i'm standing here and egypt security forces have put up a 12-foot high call of cinder block to keep that alleyway safe where the embassy is. the public services section which visitors use is closed today. that part of it is closed off. the embassy itself has not been targeted but it is part of a rough taeub rough neighborhood around tahrir square where protestors are throwing rocks and police are firing teargas. two buildings were set on fire, those blazes are now out. warnings issued to all americans to avoid the downtown area over the next few days due to the unrest, bill. bill: when will the new egyptian president morsi speak, do we know that, steve? >> reporter: we expect to hear from him on national television later tonight in a taped address. he's likely to introduce a new constitution, and that constitution could either make things better on the streets or it could inflame more protests, really depending on how hard line an islamist slant that constitution takes. we are likely to see more street protests here in egypt, b
